The specific embodiment
For further setting forth the present invention, reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, the specific embodiment, structure, feature and effect thereof to proposing according to the present invention, be described in detail as follows.
Figure 1 shows that the flow chart that the job practices of steel corbel is set on concrete frame trestle of the present invention, Figure 2 shows that the structure chart that steel corbel is set on concrete frame trestle of the present invention.Please refer to Fig. 1 and Fig. 2, the job practices of steel corbel be set on concrete frame trestle of the present invention, comprise step:
The first step, assembling reinforcement forms cage of reinforcement 10.The structure of cage of reinforcement 10 is identical with the shape of concrete frame trestle 20.
Second step, according to design elevation fixing at least four pre embedded bolts 30 at least one side of cage of reinforcement 10.Concrete, 2 pre embedded bolts 30 are set in the one side of cage of reinforcement 10, one end 31 of pre embedded bolt 30 is fixed with the reinforcing bar spot welding in cage of reinforcement 10, and the other end 32 of pre embedded bolt 30 exposes outside cage of reinforcement 10.Understandable, also can on the two sides of cage of reinforcement 10, three or four sides, pre embedded bolt 30 be set, the quantity of pre embedded bolt 30, also not as limit, can increase as required or reduce.
The 3rd step, at the outside of cage of reinforcement 10 installation form, the part of exposing outside template of pre embedded bolt 30 is wound around protection with adhesive plaster.
The 4th step, concreting in cage of reinforcement 10, and vibrated concrete.
The 5th step, after concrete reaches design strength, stripping, forms concrete frame trestle 20.Generally, concrete frame trestle 20 general about 7 days can form removal.
The 6th step after the adhesive plaster on pre embedded bolt 30 is removed, is installed the steel corbel 40 of making on concrete frame trestle 20.The schematic perspective view that Figure 3 shows that steel corbel of the present invention, refers to Fig. 3, and steel corbel 40 is provided with some bolts hole 44, and steel corbel 40 is fixed on pre embedded bolt 30 by bolt hole 44 is adjustable
Figure 4 shows that the schematic diagram of the connected mode of steel corbel of the present invention and pre embedded bolt.Please with reference to Fig. 1 to Fig. 4, concrete frame trestle 20 is provided with a crossbeam 50, and crossbeam 50 can be truss, crane girder or technique track.
When only having a side of concrete frame trestle 20 to be provided with pre embedded bolt 30, the one end 31 that is positioned at cage of reinforcement 10 is bending, and to increase pre embedded bolt 30 and concrete snap-in force, thereby pre embedded bolt 30 can be anchored in concrete frame trestle 20.The adhesive plaster for part outside template that exposes of pre embedded bolt 30 is wound around protection, thereby can prevent that pre embedded bolt 30 is corroded gets rusty.On pre embedded bolt 30, be also provided with external screw thread, and be fixed steel corbel 40 with packing ring (not shown), nut 60.
In one embodiment of the invention, every pre embedded bolt 30 can bear at least carrying capacity of 20KN.
In one embodiment of the invention, the top board 41 of steel corbel 40, fixed head 42 and two side plates 43 adopt Q235 or Q345 grade steel plate material to make, and the round steel that pre embedded bolt 30 adopts diameter to be not less than 16mm is made.
In one embodiment of the invention, the top board 41 of steel corbel 40, fixed head 42 and two side plates 43 are hot-dip galvanizing sheet steel, thereby make the steel corbel 40 can be antiseptic and rustproof.
In sum, on concrete frame trestle of the present invention, arrange in the job practices of steel corbel, first form concrete frame trestle, and form pre embedded bolt in concrete frame trestle, and then on concrete frame trestle, steel corbel is installed, steel corbel is fixed on pre embedded bolt by the bolt hole on it is adjustable, thereby can reduce cage of reinforcement, the reinforcing bar density at steel corbel place is being set, facilitated and concretely built and vibrate, guaranteed concreting and the quality of vibrating; And do not need to make profiled template, reduced the complexity of work, improved work efficiency.Concrete frame trestle of the present invention also can make convenience such as truss, crane girder, technique rail beam, efficiently, fast, be mounted on steel corbel reliably.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be not depart from technical solution of the present invention content, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
